London iTunes festival 2013's lineup so far is like music to our ears!

Justin Timberlake, Jessie J, Thirty Seconds to Mars, and Jack Johnson will lead the pack of STELLAR musicians and their eargasmic sounds.

While the WHOLE lineup of 60 acts has yet to be announced, we DO know that performers like Primal Scream, Jake Bugg, Phoenix, and Queens Of The Stone Age will also be serving up some AH-mazing beats this September at the Apple sponsored month-long fest.
